Ajax, sometimes written as AJAX (shorthand for
asynchronous JavaScript + XML), is a group of interrelated web
development techniques used on the client-side to create interactive web
applications or rich Internet applications. With Ajax, web applications
can retrieve data from the server asynchronously in the background
without interfering with the display and behavior of the existing page.
The use of Ajax has led to an increase in interactive animation on web
pages and better quality of Web services thanks to the asynchronous
mode. Data is retrieved using the XMLHttpRequest object. Despite the
name, the use of JavaScript and XML is not actually required, nor do the
requests need to be asynchronous.

AJAX provides Web developers with plenty of opportunities to enhance the
user experience and improve the performance of their websites. There are
countless ways that AJAX can be used, and fortunately there are plenty
of good and useful AJAX tutorials out there to help you with your own
implementation.

This post serves as a collection of useful tutorials on working with
AJAX in a wide variety of ways. You’ll find tutorials on working with
forms, building shopping carts, creating chat features, working with
log-ins and usernames and much more.

Ajax a short form of Asynchronous JavaScript and XML is a set of
techniques used by many modern and popular web sites. This technique
allows portions of a Web page to be updated without refreshing the
entire page and to increase the web page’s interactivity, speed, and
usability that is a significant advance in the development of websites
and web-based applications. For example, a site might allow you to rate
a product or item by clicking on a star image. With Ajax, your vote
could be registered without having to load the entire page again. If you
already know about Javascript, HTML, CSS and XML then you will need to
spend your 1 hour to start with AJAX.

Here is the list of 23 Ultimate Collection Of Useful Ajax Tutorials &
Resources that includes some useful tutorials and few great resources
like script, examples etc. We are hoping that you will learn further on
Ajax after reading out this post.

Web-developers can create amazing web-applications with AJAX. Stikkit,
Netvibes, GMail and dozens of further web-projects offer a new level of
interactivity we’ve used to give up the idea of. Modern web-applications
can be designed with enhanced user interfaces and functionalities, which
used to be the privelege of professional desktop-applications. AJAX
makes it possible to create more interactive, more responsive and more
flexible web-solutions. And it’s the first step towards rich internet
applications of the future.

When it comes to design of modern web-applications, Ajax is considered
as a standard approach. Interactive solutions for lightboxes, form
validation, navigation, search, tooltips and tables are developed using
Ajax libraries and nifty Ajax scripts. Ajax is useful and powerful.
However, when using Ajax, one should keep in mind its drawbacks in terms
of usability and accessibility. With an extensive use of Ajax, you can
easily confuse your visitors offering too much control and too many
features.

Web users love informative clues. Whatever questions and
misunderstandings might occur - delivering precise answers immediately
is the primary task a responsive user interface should be able to cope
with. To do that, developers have to consider subtle and well-thought
tooltips - used correctly, they can greatly improve user experience and
help users to get things done. In Web such “responsive” hints can be
provided by tooltips. E.g., unclear input fields in web forms are
perfect examples of a situation you might be willing to use a tooltip
for.

Most of solutions are JavaScript- and AJAX-based, however we’ve also
managed to find some lightweight CSS-based solutions. To install and use
the script, it’s often enough to include the JavaScript library in the
source code and provide the hint as plain text within the
“title”-attribute. Sometimes you can also insert URLs, images, tables
and further elements - basically, it can be almost everything you’d ever
wanted it to be.

Ajax is a catchy name for a type of programming made popular in 2005 by
Google and other big web developers. Ajax loosely stands for
Asynchronous Javascript And XML, but that just sounds like techno jargon
to many people.
